Volatility of fluids

[LurmClaxton]

Hello everyone,

I'm trying to rank various fluids typically piped around a refinery by their tendency to vaporize.

I can do it by gut/experience but I'd like to approach things in a more scientific way. What fluid characteristic would be the best to use? I thought vapour pressure but I'm struggling to find reliable numbers/charts.

Can anyone offer any advice or point me towards a good source for fluid characteristics.

Best Regards

Lurmy

RVP ( Reid Vapor Pressure ) or TVP ( true vapor pressure ) found in the MSDS?
